floating point multiplication

Hi

I am trying to do a floating point multiplication as below

float c = float a * float b;

I have this piece of code being executed from

1) Flash  : it took 130 nano seconds

2) RAM : it took 128 nano seconds

I also had Fast RTS FPU library handling the multiplication.

I am wondering if execution from RAM would be faster than from FLASH but in reality I am not seeing any difference.

Am I doing something wrong?

Thanks

Ram
